Re: [CentOS] blocking outgoing ports with iptables

Hi,

I'm using the generic system-config-securitylevel-tui program on a remote server to configure my firewall. So far it's been fairly decent, allowing me to open up ports and whatnot. But I want to start blocking a couple of outgoing ports on my machine. I want to lock it down so the only traffic going in our out of my machine is stuff that I specify.

Is there a way to do this with the system-config-securitylevel program? If not, what do you recommend I use to configure the firewall?

thanks, ajay

I've never seen a way block outbound ports using the config tool. If you are comfortable with the iptables syntax, you could edit /etc/sysconfig/iptables to your liking and then restart the iptables service.
